Abstract

The invention discloses a super-resolution method and device of an image, a storage medium and an electronic device. The super-resolution method comprises the steps: acquiring a first image to be subjected to super-resolution processing, wherein the first image carries first interference information; and performing interference filtering processing and super-resolution processing on the first image through a first model to obtain a second image, wherein the first model is a neural network model trained in advance by using an image carrying second interference information, and the resolution ofthe second image is higher than that of the first image and the second image does not carry the first interference information in the first image. According to the invention, the technical problem oflow definition of the image obtained by super-resolution in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image super-resolution method and device, a storage medium, and an electronic device. Background technique [0002] As an important form of information for perceiving the world, images are rich and detailed in their content, which directly determines the level of detail in the perceived content. The higher the pixel density on the image unit scale, the clearer the image, the stronger the ability to express details, and the richer the perceived information, which is a high-resolution image. The super-resolution reconstruction of images has been studied in many fields, such as remote sensing images, satellite imaging, medical images, and some high-definition display fields. [0003] The method of improving the resolution of the image mainly relies on improving the sensor manufacturing process to reduce the pixel size or increase the number of pixels per unit area. Howev...
